you should ensure that the Attendance list provided to the For loop is exactly the same both during render and rewind.
then, irrespective of the number of rows the render/rewind sequence will be exactly the same. so the checkbox on render will correspond to the same Attendance object when the rewind happens. then you just need to bind the checkbox value to a currentAttendance.persentognl On 8/18/06, zqzuk <[EMAIL PROTECTED]> wrote:
Hi, the scenario is that i have a collection of Attendance objects- for example, Attendance(Student s, String class, String attended) - to be displayed on a page. and i would like a checkbox (or other components whichever appropriate) for each row. so if the student attended the class, user can tick the box. user then ticks those boxes if the student attended the class, then finally click a button "save", and program will figure out which Attendance objects are changed and commit database transactions. so something like this: ----------------------------------------------------------------------- Student class attended ----------------------------------------------------------------------- Bob math ticked Henry physics ticked Anne english ticked Nick history unticked [Save Button] ---------------------------------------------------------------------- each row above represents an Attendance object. the problem is, because the number of rows are variant, so i m using a For component to produce these rows automatcally. but how can i know which checkboxex are ticked, and which checkbox is for which row? as these boxex are produced at runtime and assigned different names at runtime isnt it? unlike the DirectLink component which can pass parameters such as the object's id, how does a checkbox (or if other appropriate components) identify the row? i could use directlink instead and open up another window where user tick the box in a separate page for each Attendance row, but that would be bad design... any suggestions pleaes, thanks very much! -- View this message in context: http://www.nabble.com/hi%2C-is-it-possible-to-do-this-with-tapestry...-tf2126696.html#a5867937 Sent from the Tapestry - User forum at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
